Observation of Anderson Localization in Ultrathin Films of Three-Dimensional Topological Insulators
Observation of Anderson Localization in Ultrathin Films of Three-Dimensional Topological Insulators
Anderson localization, the absence of diffusive transport in disordered systems, has been manifested as hopping transport in numerous electronic systems, whereas in recently discovered topological insulators it has not been directly observed. Here, we report experimental demonstration of a crossover from diffusive transport in the weak antilocalization regime to variable …
